Abstract:

Huanglongchang structure is located at the cross point of in Dabashan fold belt and east arc fold belt of the Sichuan
Basin,which is complex in the structure and the tectonic movement. There are two types of fold belt systems in the deep and
shallow underground. Through the analysis of seismic slice and horizontal slice,the type of the fracture and its distribution
feature were recognized,and the corresponding texture style was estblished. Some forward modeling on these structures have
been done to verify the rationality of them. Based on the study,we analyse the tectonic movement and its characteristics,
and determined the time of the tectonic development and structure evolution feature of Huanglongchang. the development of
structures in Huanglongchang is classified four stages:Early Indosinian low uplift period,the late Indosinian great thrust fold
development period,Yanshan epoch small extrusion fracture development period,and the Himalayan inherited uplift period.

Key words: Sichuan Basin, Huanglongchang Area, Jianglinjiang Formation, structure, tectonic movement
